FAQ: Frequently Asked Questions
Why is nitric oxide (NO) monitoring important?
Nitric oxide (NO) is a gas belonging to the nitrogen oxides (NOx) family and is mainly produced by high-temperature combustion processes. Monitoring NO helps detect and characterise emissions associated with combustion, engines and industrial processes. NO is also relevant to air quality because it can be oxidised in the atmosphere to form nitrogen dioxide (NO₂).
In which environments and applications is NO concentration monitoring useful?
NO measurement is useful in environments potentially affected by emissions from combustion processes, traffic, engines or industrial activities. Indoors, it can contribute to air quality assessment in technical areas, workplaces and other spaces potentially influenced by these sources. LSI LASTEM also identifies IEQ, waste-cycle applications and indoor monitoring among the applications for its NO sensor range.
How does the LSI LASTEM nitric oxide sensor work?
LSI LASTEM NO sensors use an electrochemical cell to measure nitric oxide concentration in air. The range covers 0–300 ppm, with a resolution of 0.5 ppm, declared repeatability of ±2% of reading and a T90 response time below 40 seconds. The indicative sensor life is approximately 2 years.
How can LSI LASTEM NO sensors be integrated into a monitoring system?
LSI LASTEM NO sensors can be used for both portable measurement surveys and fixed installations. Models are available with mV output and MiniDIN connectors for LSI LASTEM data loggers, as well as versions with 4–20 mA and RS485 Modbus that can also be integrated into third-party acquisition systems. NO can also be monitored alongside NO₂ and other gases to provide a more comprehensive multiparameter assessment of air quality.
